The main parts oi1v the machine, as shown in the beorelmentionedapplication` consist of a bed plate 'Z4- above which is a flat ring 26supported by standards Q5, 25. The cylinder needle bed 28 is supportedby under brackets 27, and the flat needle bed() by a central bracket9,9. in upper stationary ring 32 is carried by curved standards 31, 31,and is provided with inside and outside dovetail guide Ways.

A system of driving gear comprising a shaft 33. pulley 35` pinion 36.,gear Wheel 37, miter Wheels 39. el() and 41 aetuates the cam carrier 137oi? the horizontal needle bed and the cam carrierSS oit the cylinderneedle bed through the medium of the shaft connected to miter wheel Ll()and a sleeve connected to the miter Wheel 4-1, the arrangement beingsuch that the tivo cam carriers rotate in opposite directions.

The other cam carriers 73 oit the cylinder needle bed, shonf'n in Figs.2 and 3, and 74, partly shown in 3. are also driven by the same gear inopposite directions. The cam carriers 88 of the cylinder needle bed and74rof the horizontal needle bed travel in the same direction7 and theouter cam llt) Vof the carriers 73 and 74 are adapted toproduce ordinaryknit stitches as shown in said patent and need no further descriptionhere. The cams ofthe carrier 88 acting on the lower butts of the needlesof the cylinder bed and the cams of the carrier 137 acting 'on the outerbutts of the horizontal bed are i the ones to which Vthis inventionrelates, the

. new mechanism being designed to automatically actuate these cams, ashereafter described.A A means for operating the cam carriers is diagrammatically illustrated in ln this view the shaft 42 has se eurerL toits upper end a pinion 75 which ineshes into gear 7 5a of carrier 73,and also a pinion 76 which meshes into gear 7 6a on a sleeve 77surrounding the vertical shaft 7 7 lalear the upper end of the sleeveconnectcd'to the niiter wheel 41 is a pinion 78 acting in the internalgear wheel'78a of the lower cam carrier 88 of thecylinder bed, and apinion 79 acting in the gear wheel 79 secured to the lower end of theshaft 7 7a, to

thev upper end of -which is connected, by a spider frame, the outer camcarrier`137 of ,they horizontal needle bed. These gear wheels and.pinions are Yproportioned to cause the cani carriers to travel atuniform speed.

- As set forth in the before mentioned patent the needles of thetwo'needlebeds are divided into two groups, there being gaps orblanlrspaces between the ends of the groups. rlhe' cams continuouslyrotated pass over and Yact on the groups or needles alternately and passby one another at the blank spaces between the groups oi1 needles, andas there are :tour sets of cams, traveling in Vpairs in oppositedirections, and four groups of needles,pbeing actuated.Y in pairs, thatis adj acent groups ci the two needle beds together, all olthe groups ofneedles are simultaneously operated and the only loss of time in theknitting process is when the earns are passing from one group to theYother over the comparatively short gaps in the needle beds between thegroups of needles. Y rThe mechanism indicated by numerals 48, 49, 86,87, 200, 202, 203, 204, vand 206 control the needle racking devices, andthe parts marked 243, 244, 245 represent the feeding meansy for vthegoods as produced by the knitting bed-s. All of these parts so farreferred to being outside this invention will not be'further described.l

The direct means for operating the needle cam controllers and theseparating thread Y mal knitting positions.

layer, constituting the essential features of this invention, consist oftwo vertically sliding bars 44 and 45, which are actuated by a system ofpattern chains 46, 47, 50 and 51, and the connecting mechanism 61, 62,63, 64, 71, 72, all fully described in the before-mentioned application.

There are two sets of' cams for each of the two sets of needles, theneedles of each sei, that is the cylinder'bed needles and the horizontalbed needles are divided into two groups, and all of the needles areprovided with two butts. The cam carrier for the upper butts ot thecylinder bed .needles is shown at 73, Fig. 3, and a cani carrier 74 'torthe inner butts oit the horizontal hed needles is also used; neither olthese carriers nor the cams carried by them form any part of thisinvention. heilig included in and t'ully described in. nl v U. S.Letters PatontA No. 868,276, dated Oei'. 15, 1907.

The vertical sliding rod 44, hold and guided in bearings has connectedto its upper end a lever 55 which controls thc operating device of thecam 138 of the horizontal needle hed that is active when the separatingthread is being laid; at its central part thelever 57 for actuating theseparating thread device, and at its lower part the lever 59 forcontrolling the actuating device of the cam of the cylinder needle bed,which is also active when the separating thread is being laid. The othervertical rod 45 is connected at its upper cud to a lever 56 whichcontrols cams 139, 140 and 141 of the horizontal needle bed, and isconnected at its lower part to the lever 58 which controls the cams 112,113. 114 of the cylinder needle bed. These levers are respectivelycentrally fulcrunied to suitable brackets on the Jframe, lever 55 at 80,lever 56 at 81, lever 57 at 82, lever 58 at 83 and lever 59 at 84, seeFig. 3, in which view they are shown in norrlhe outer ends of theselevers pass through slots in the rods 44, 45, and are caused to movewith the rods by pins 46 acting in elongated holes formed in the ends ofthe levers.

Referring to Figs. 18 to 28, 88 indicates the cani carrier for thecylinder needle bed attached to a ring 89, Fig. 3, which is continuouslyrotated. The cams for controlling the needles of the cylinder needle bedare carried on a frame 91 secured by screws 92 to the cani carrier 88.The cani system for forming elongated or tuck stitches consists of atriangular cam 112 at the end of a long cam 113 for depressing theneedles after their butts have passed oil the cam 113. In the face ofcam 113 is placed a triangular latch 114 pivoted at 115 to the traine 91and so formed that when in downward position one of its sides forms acontinuation of the face of cam 113 so that the loops held by the--needles are not cast oli?, and when it is raised itconstitutes theriser for the needles to cast oli' the retained loops when the nextsucceeding course is formed. The cam 112 is also set in upper positionat this time, thus forming less slack, reducing the amount of yarn inthe loops, than that when a tuck 7 stitch is being formed with said camin lower positions. lThe cam 112 is carried on the inner end of a rod126 with a guide plate 93 iitted to slide in an angularly arrangedbearing on the inner side of the frame 91., the outer end of said rodbeing attached to a slide 122 held in a guideway 123 on the outer sideof the iframe 91 correspondingly arranged to the angular bearing ot theplate 93 to which the cani 112 taehed. The lower end ot the slide 122 isshaped. to be acted upon by an incline recess 91 Ain the edge oit aplate 95 secured by screws 95 to a. slide 97, 'which` by slotted.openings 98, is held on the cani carrier 88 by screws 99. The head ofone o1 the scrmvs 99 under the plate 95 is seated in a delnfession.around .its slot 98, as shown in liligs. 19 and rlllhe holes in thcplate 95 through which the screws 99 pass are verti cally elongated toprovide for adjustment ot said plate for properly determining the amountof movement of the cam 112; the slide 122 being held against the activeincline surface of the plate 95 by means ott a spring 128 attached'tothe rod 126, see Fig. 21. Gn the inner side of the slide 97 shown inFigs. 18, 19, 20 secured by screws 100, is bracket piece 101 having itsinner end camshaped or inclined at 102 to act on a pin 132 extending`from the latch 114 through a curved slot formed in the inner partei:lthe iframe 91; the arrangement being such that whenV the slide is movedtoward the right both the cam 112 and latch. 114 are raised, and theymove down when the slide is set in reverse direction.

To facilitate setting the bracket piece 101 it may be secured to theouter tace of slide 97, as shown at Fig. 24, being held thereon byscrews 103 passing through a long slot 104. in the bracket piece 101.lThe upper edge '105 above the active incline edge 102, which holds thelatch in upper position, is also shown longer in this view than in theother views. Slot 1.04 is suciently longto set the edge 105 sothat itwill remain under the pin 132 and hold the latch out in casting oilposition all the time it desired.

The slide .97 is provided with an open slot bearing. between 'twoextending horns 100, in which a rounded. end o1 a leverarm 107 works.said. lever arin being by a stud bolt 108 pivotally connected to anextension 109 of the bracket 110 secured by screws to the cam carrier88. rThis bracket 11G carries parts oit the thread controlling`mechanism as hereafter described. The lever arm is provided with twotappets 117, 118, near its .inox/ting. the cani 112 down and the latch114` up in active position, as shown by the dotted .lines 114', see Fig.20, and these parts so remain until the lever 58 is moved down to co-actwith the tappet 118 when ctuclr stitches are to be made, thus settingthe arm 107 as shown by the full lines and actuating cam 112 and latch114, as beforedescribed. The "tucli7 stitch forming mechanism oit thehorizontal lied ol .needles is controlled. by the lever 50, which beingconnected. to the if'ertical rod 45 acts in unison with the lever 58.lhe .needle cams act on the outer butts oit theneedles and are in allessential respectrsl structurally and operatively sini.;- lar to thecorresponding cams o1.l the cylindrical needle bed, previouslydescriliied. They are attached to a lraine plate 142 ser cured to thecam carrier 137, by screws 143, diainetrically opposite to thecontrolling device that is actuated by the lever 56;` they comprise along cam 140 provided with a pivoted latch 141, and a triangular cain139 adapted to be raised and lowered relative to the long cam, and themechanism for directly actuating the cams is similar to that applied tothe cams 112, 113, and 114-.

Referring to Figs. 7 to 13 it .ie seen that cam 189 is carried on thelower end ot' a rod 126 and has a guide piece 137u which slides in anangularly arranged slot in the under plate ot the traine 142. The upperend of rod 120a is secured to a slide 122 held in a guide-way 123 andhaving its inner end shaped to be acted upon by the cam surface 184 of aplate 185 secured by screws. 185 to a sen'iicircular dat operating ringplate 155, the holes in plate 1.85 through which the screws 186 passbeing slotted to provide for adjustnient of' action ot the cam iliace184 on the slide 1221. "1 spring 1.28 acting' on the rod 126 holds thepoint oilE the slide 122 against the cam surface oit plate 185. rllheseinieircular Vfiat plate has slots at its ends through which screws1.50 pass to hold the plate on the cani carrier and act as guidestherefor. The cam latch 141 moved into outer position by a cam ledge187, acting on the stud 132 oi the latch and tor1ning part of a bracket188 secured by screws to the under side o1.: the semicircular plate 155;the arrangement being such that when the plate 155 is moved in aright-hand direction relative to the cani carrier 137 the latch 141 and.earn 139 are raised or moved outwardly. -A modification of the bracketsuflicient distance for the edge 105a vto reend of a lever arm 192.

mainunder the stud 132L and hold the latch 141 out when the flat ringplate 155 is moved .into the position shown in the drawings.

To tie opposite end of the flat ring plate 155 is'vsecured a shortstandard lug 189, to which is pivot-ally connected, by a screw stud 190,one end of a link 191, the other end of which is pivotally connected tothe This arm rocks on a screw stud 193 secured toV a standard 194 whichis connected to the cani carrier 137. The yupper part of this lever armabove the stud 193 is provided with a slotted bearing 195, in which actsthe rounded end of an arm 196 fitted to rock on a vertical post 197extending upwardly from the top of the standard 194, and this arm isprovided with or connected to two tappets 19S `and 199 arranged so thatin their paths of travel they will contact with and be acted upon by thecontrolling` lever 56. These tappets are in different horizontal planes,as shown in Fig. S, the upper one 199 being acted upon, as the .canicarrier rotates in direction indicated by the lever 56, when said leverispin upper normal position and the lower one-is actuated'by the lever56 when its operating end is depressed by the upward movement of the rod45. This latter condition arises whenV tuch stitches are to be made. Thecams and other parts then occupy the positions-shown in the drawings.Assuming that the cam carrier 137 has made one or more revolutionscausing the formation of one or more tuck stitches, or the retention oftwo or more loops on the needles, and that the lever 56 has been movedinto upper position, as shown at Fig. 3, the tappet 199 will now strikethe leverr 56, be moved into position of the dotted lines 1992, the arm192 into position of the dotted lines 192a and the cam ledges 184andf187 -moved forwardly. The cam l139 will then be moved up and thelatch 141v raised into active position and so remain until tuck stitchesare again to be formed.

rlhe lever 57 controls the separating thread mechanism and in its upperinactive position moves the upper tappet 210 moving it, as shown in Fig.5, to bring the wedge 211 behind the block 212 of the spring latch 172andr so hold said latch out of action. This tappet 210 with the tappet213 arranged in a lower plane are connected to or form a part of ahorizontal arm 214, which, by a pivotal connection 215 is carried by auextension 2,16 of a frame 217 fastened by screwsto the top of thebracket 116 which is secured to the lower cam carrier of the cylinderneedle bed. The free end of the arm 214 is rounded and works in an openIslot bearing 218 extending from a slide 219. This slide has guide slotsformed at its ends and is held against the side of frame 217 by screws220. The wedge 211 is formed at the upper part of a plate 221 which issecured by screws to the slide 219. The latch 172 is fitted to slide ina head 222 forming a part of the frame 217 and sui'- rounding its stem,to which the block 212 is attached, is a spring 177 acting to force thelatch out when the wedge 211 is withdrawn from the block 212. Thisoccurs when the active end of lever 57 is depressed by the upwardmovement of the. rod 4l. The tappet 213 then strikes the lever and thearm 214 is set in the position shown by the dotted lines 214% carryingthe slide 219 with it, moving the wedge 211 away from the block 212 andso freeing the latch 172 to be forced out by its spring 177 ln thisouter position the latch contacts with the lug 170 of the separatingthread carrier block 161 and moves the thread carrier around 0n theguide-way ring At the next revolution of the cani carrier the lever 57is up in position to be struck by the tappet 210, which again causes thewedge 211 to withdraw the latch to miss the lug 170.

Y Referring to Figs. 29, 30 and 31. the twoseparating thread carriers160 and 160 are attached to blocks 161 and tted to slide on a dove-tailguide way 162 formed on the inner side of the top stationary ring Onthis guideway are also held two blocks 163. which carry cam ledges 164and 165, said blocks being held in position on opposite sides of thering 32 by set screws. as shown in Figs. 29 and 30. The outer side ofring` 32 is also formed with a dove-tail to hold blocks 166, which innormal arrangement and adjustment 0f the various parts of the machineare held, by set screws, in line with the blocks 163. Each of the blocks166 carry cam ledges 167 and 168, whose functions with those of ledges164 and 165 will be hereafter described. The blocks 161 have at theirupper inner sides a lug 169 and at their lower outer .sides a lug 170,and these lugs are acted upon by spring actuated latches 171 and 172respectively, latch 171 being held in a head 173 on the upper part of abracket 174 secured to the outer cam ring 137 of the horizontal needlebed. Said latch is forced into and held in outer position by a spring175. The latch 172 is similarly held in a head 176 and forced intooutward position b v a spring 177, said head 176 being carried by thelower cam carrier S8 of the cylinder needle bed, and this latch isautomatically actuated as before described. lTo elucidate the manner 0flaying nannies or feeding the separating threads and their relation tothe regular knitting threads, the carriers for the regular threads, inall essere tial respects similar to the carriers 160, 16061, are shownby dotted lines 178 and 179 and are provided with lugs 180 and 181arranged to co-act with spring actuated latches 182 and 188respectively, also shown by dotted- -lines rlhe latch 182 is carried bythe cam carrier 187 and the latch 188 carried by the lower cylinder' camcarrier. The positions of these latches permanently fixed relative tothe latches 171 and 172 respectively are substantially as shown.

Now, when ordinary knitting is being done on the machine, the separatingthri ad controlling latch is held out oit action as shown. W ith thethread carriers in the po-V sitions indicated, the latch 188 will pickup carrier 178 and move it somewhat less than halt-way around the ring82, leaving it adjacent the block 166 by the latch riding up the cam endof the ledge 168, and simulianeously the latch 182 picks up the carrier179 and moves it in the opposite direction to position adjacent thecarrier 160L and leaves it there by the Ylatch 182 riding` up on theledge 165. The latches continuing their circular movement, the latch 188slides oil' the ledge 168, picks up the carrier 179 and returns it toits original position; and the latch 182 slides oil the ledge 165, picksup carrier 178 andreturns it to the position shown. rl`hus in onerevolution o1' the machine two rows or layers of stitches are formed ateach side ci the machine. r1`he two groups of needles in both thecylinder and horizontal. beds are actuated by their aims to adequatelyco-act with the thread carriers. When the separating threads are to beinserted at the completion o1 a knitted article or section oil? thegoods formed, the latch 172 automatically freed and picks up the threadcarrier 160 at about the same time the latch 188 picks up the carrier 178, and at the same time the latch 182 moves the thread carrier 17 9, allof said carriers being now moved at the opposite side of the ringl 82.Latch 188 now picks up carrier 179, latch 172 picks up carrier 16WDlatch 171 takes carrier 180 and latch 182 takes carrier 178, so at thetermination oii' this half revo-- lution of the machine the carriersoccupy the positions shown with the exception of carrier 1GOn which isadjacent the carrier 178, but it is. during the next halt revolution,returned by the latch 171 to its original position, as shown. nt thetermination of one i'ull revolution the latch 172 is automatically movedout of action, and it will be seen that the separatingthread carriers160, 160 in making a forward and backward movement present theirthreadsto the needles between two knit courses of the regular threads. Theupper cam ledges on the wr i: .Elta

inside oi' the ring and the lower ones on the outside of the ringcontrol the separating thread latches, and the upper ledges on theoutside of the ring and the lower ones on the ."iside o1` the ringcontrol the regular` ordinary knitting thread latches.

yThe latch 188 is spring actuated similar to the other thread carrying1latches; it is held in a head 228 secured to the top oit the bracket11G, a short distance ahead or' the latch 172. rl`he Vstem of latch 188is provided with thumb piece and a pin 2241 which works in a slot 225 inthe head 228 to hold the latch in operative position. When it is desiredto put the latch out of action it is drawn back by the thumb piece,turned i'or the pin to rest against the end oi the head, as shown. Oneach o1' the cam carriers 88 and 187 is a cani that is set in operativeposition only when the separating thread is being laid. rllhe cam 90 ofthe cam carrier 88 of the cylinder needle bed is secured to the innerend of a rod which has a sliding bearing in the traine. 91, and has atits outer end a block 227. A spring 228 forces and holds the cam inouter operative position. A slide 229 held on the carrier 88 by screws280 has attached to it a plate 281 having a wedge-shaped end 282 adaptedto pass behind tlie block 227 and draw the cam 90 out of action with theneedles. This slide'is controlled by an arm 288, the end of which worksin an open slot bearing on the slide, said arm being secured to a shortshait 2M- U11 having a bearing in a standard 285 secured to the carrier88. To the other end of the shaft 284C are fastenedv the tappets 286,287, which are acted upon by the lever 59, the upper one 286, shownat'liig. 25, being about to strike the lever, and the eifect oit' thiswill be to move this tappet and arm 288, as shown by the dotted linesand so force the wedge 282 under the block 227. The cam 90 is thus movedout Oi active position. At the same time that the lever 57 moved to makethe separating thread controlling means active, the lever 59 is set toact on the tappet 287, causing the wedge 282 to be drawn away from theblock 227, thus allowing the spring 228 to set the cam 90 into activeposition. The operating lever is also at the same time set to cause thecam 188 oit the cani carrier 187 to act on the needles of the.horizontal needle bed. rl`his cam is :tastened to a rod 91L passingvertically through the traine 14:2 and having a block 288 se cured toits upper end, and a spring 92L surrounding it above and bearing on thecam, to hold the cam in outer operative position, as shown at Fig. 17. Awedge plate 289 is secured to one end ot a semicircular tlat bar 1415attached to and fitted to slide on the cam carrier at the opposite sideto and in the same manner as the semicircular flat sliding bar or plate155. C@crews 1li-8 on the cam carrier pass through slots in the bar 145.r 0n the other end of the bar 145 is secured a lug 147 to which isconnected one end of alink 148, its other end being connected to the.lever arm 149. This lever arm rocks on the screw 'stud 198 on thestandard 194. The upper part 250 ot the lever arm 149 has on openbearing 251 in which the rounded end of an arm 252 works, and isprovided with or connected to two tappets 253 254. rlhe arm 252 isfitted to rock on the vertical stud 197, with the tappets so located asto contact withl the leverV 55 as the cam carrier 137 rotates. The screwstud 193 also carries the lever arm 192'and the vertical ,st-ud`197 alsocarries the arm 196 and tappets 198 and 199 of the controlling device otthe other cams on the carrier 187 betere described. TheV last actionotthe lever 55 was, by acting on the tappet 253, to set the parts as shownby the full lines. The wedge 239 was thenwithdrawn from the head 238 andthe cam 138 set out and held in active position to operate the needlesto form the loops ot the separating thread. As seen by Fig. 14, thetappet 254 will next co-act with thellever 55 which has now been raisedinto the path of travel of said tappet, moving it, the arm 252, arm. 149and connected parts into position shown by dotted lines, the wedge 239then being set under the head 238 and the cam 138 drawn from action withthe needles, and it is so held until a separating thread has again to beapplied4 to the knitted goods. i rihe tappets of each pair hereinreferred to are integral or rigidly connected and are located onopposite sides of a plane passing through their common axis, thuscausing them, when acted upon in the same direction, toreeiprocate thedevices which they control.
